FAQ:

1Have you ever sold your products to companies in my country?

Of course, we have customers in all general PV markets, but I think we should expand our market share along with the market growth.

2When did your company set up?  You are a new company, how can I believe your quality?

We entered into Solar PV industry in 2005, now we have several plants in manufacturing of a-Si and c-Si panels, and our capacity is 220MW per year. Till now we have already passed all the tests by authorized laboratories, e.g. TUV, VDE, UL.

Q:My family and I are looking into solar panels for our home. But I'm unsure how it would be priced. This month our home used ,623 kwh. The solar panel company said we should expect $6-$9 per watt used. What would that put as at?
With out doing the math,, I think I would ask the solar panel company to explain it to you as they are trying to sell it to you. And see if you have some sort of warranty of savings. Make them work for the sale!!
Q:Can solar panels be installed on electric fences?
Yes, solar panels can be installed on electric fences. The panels can provide the necessary power to keep the electric fence operational without relying on traditional electrical sources.
Q:So during the day, electricity is on, everything is on and working fine. But at night where there is no sunlight does all the electricity shut down for the night? So there is no light on for me during the night, or I can't watch tv at night? Is it also true that with solar panels, your bills are less expensive. Can someone please tell me these things
But at night where there is no sunlight does all the electricity shut down for the night? Electrical production shuts down, but most solar electric systems have some way of storing power. There are two main types of storage: . Grid tie. Basically this uses the power grid as a virtual battery. You produce extra power during sunlight hours to sell to the grid (other people use it) and you buy power from the grid when the sun doesn't shine. This is usually the most economical system, but whether you save money depends on a lot of things like: cost of installation, location, government subsidies how much you get for the electricity you sell buy. In other words, the details matter. Mostly location, which determines how much sunlight you get, electric rates, and subsidies. 2. Batteries. Usually a large bank of deep cycle lead acid batteries. Usually only used in off-grid systems and the cost of electricity is usually not competitive with grid electricity.
Q:Can solar panels be damaged by hail or other weather conditions?
Yes, solar panels can be damaged by hail or other severe weather conditions such as strong winds, heavy rain, or snowstorms. Hail can cause cracks, dents, or shattered glass on the surface of the panels, reducing their efficiency or rendering them completely ineffective. Additionally, extreme weather events like hurricanes or tornadoes can also cause structural damage to the mounting system or dislodge the panels from their position. Therefore, it is important to consider the weather conditions in a particular location and choose appropriate measures to protect solar panels from potential damage.
Q:Can solar panels be installed on a rented property?
Yes, solar panels can be installed on a rented property. However, it is important to check with the property owner or landlord before proceeding with the installation. Some landlords may have restrictions or specific guidelines for installing solar panels, while others may require written permission. It is recommended to discuss the matter with the property owner and potentially reach a mutually beneficial agreement.
Q:Can solar panels be installed on desalination plants?
Yes, solar panels can be installed on desalination plants. Solar energy can be harnessed to power the desalination process, reducing the reliance on traditional energy sources and making the plants more sustainable and environmentally friendly.
Q:Can solar panels be used in areas with high levels of bird or bat activity?
Yes, solar panels can be used in areas with high levels of bird or bat activity. However, it is important to take certain precautions to minimize the potential risks to birds and bats. These precautions may include using specific panel designs that reduce the chances of bird or bat collisions, implementing bird or bat deterrent measures, and considering the placement of the panels in areas away from known flight paths or nesting sites. By implementing these measures, solar panels can coexist with bird and bat populations while helping to generate clean, renewable energy.
Q:Can solar panels be installed on camping sites?
Yes, solar panels can be installed on camping sites. They provide a sustainable and reliable source of energy, allowing campers to power their devices and equipment while minimizing the environmental impact.
Q:Can solar panels be installed on theme parks or entertainment venues?
Yes, solar panels can be installed on theme parks or entertainment venues. In fact, many theme parks and entertainment venues around the world have already embraced solar energy as a sustainable and cost-effective solution. By installing solar panels, these venues can generate their own clean energy, reduce their carbon footprint, and save on energy costs in the long run.
Q:So you know how the bigger the surface area exposed to the heat radiation means the quicker it'll heat up.Is this what happens with solar panels, they have a large surface area exposing to the sun, so they can get more heat?
Solar panels do heat up. But that's because the radiant energy from the Sun that lies within the infrared (IR) band of energy causes the material in the panels to heat up. And that's the same for any body that has the Sun shine on it. Your face, for example, will heat up while you get a nice tan on the beach. That's due to the heat producing IR radiant energy. Now if those solar panels are supposed to heat buildings etc., that heat produced in the panels when the IR strikes them will be transferred, usually by some fluid, to floors of the rooms to be heated. And as the amount of heat generated by the Sun is proportional to the area of the solar panels, bigger areas of panel will generate more heat than smaller areas. Photoelectric solar panels are another kind. Here the interest is in the visible band of radiant energy from the Sun. Heat, from IR, is still there, but it is not the product sought by PE solar panels. The visible light photons knock off loosely bound electrons from the photoelectric material (typically silicon based) and those electrons are siphoned off as current. That's where the electrical power comes from for buildings using PE solar panels to provide their own electricity.
